STOR_POFX_PERF_STATE_CONTEXT is the structure pointed to by the Parameters parameter when a miniport's HwStorAdapterControl routine is called with a ControlType of ScsiAdapterPoFxSetPerfState.
VersionVersion of this structure. Currently set to 1.
SizeSize of this structure, in bytes. Set to sizeof(STOR_POFX_PERF_STATE_CONTEXT).
ComponentIndexThe index of the associated component.
SucceededBOOLEAN value. If the platform extension plug-in (PEP) has no part in the P-State transition (that is, only the miniport initiates the corresponding physical power state transition), then this field should always be TRUE. If the PEP plays some part in the P-State transition then this field indicates whether the PEP was successful (TRUE on success; FALSE otherwise).
ContextPointer to the same context that was passed in a call to StorPortPoFxSetPerfState. This is typically the P-state index.
